CVE-2026-81381Network attack vector

Azure DevOps token disclosure via workspace endpoint override

Published Sep 8, 2026 · Updated Sep 9, 2026

Information disclosure in GitHub Copilot Chat for Visual Studio Code before 1.136.2 allows remote attackers to steal Azure DevOps access tokens. The ADO Code Search integration accepts a workspace-controlled endpoint override and sends authenticated requests, including the user's token, to that endpoint. Exploitation requires a user signed in to Azure DevOps to open a malicious repository and trigger Code Search, after which the attacker can access resources authorized to that token.
